Yeah, I thought of that after posting my second code... but I saw you'd already posted code like that, so didn't bother with another update/post.

As a suggestion to Q.and, if using Marshall's code, I'd recommend picking the shorter file for "file2" and the longer file for "file1" -- it uses the least memory to store file2, but still requires only len(file1)+len(file2) line reads.
